Diode laser transscleral cyclophotocoagulation in the treatment of refractory glaucoma with iris melanocytoma.
Iris melanocytoma is a rare melanocytic nevus with distinctive clinical and pathologic features. Secondary glaucoma may develop rapidly and respond poorly to glaucoma medication in some cases. However, few data are available in the literature with respect to the appropriate treatment for refractory glaucoma associated with iris melanocytoma. Herein, we present a 28-year-old man with blurred vision and an elevated intraocular pressure (IOP) of 40 mmHg in his right eye while on multiple glaucoma medications. A dark brown lobulated iris mass with surrounding small pigmented lesions was noted between the 4 and 5:30 o'clock positions. Sector iridectomy was performed and pathologic examination revealed an iris melanocytoma. After surgery, antiglaucomatous medications still failed to control IOP. The patient then underwent diode laser transscleral cyclophotocoagulation (TSCP). At the last follow-up of 15 months, IOP had returned to normal without the need for medication.
